KHACHIMO ST350-SFX 350W power supply

The KHACHIMO ST350-SFX is a 350W SFX form-factor power supply built for compact system builds. It suits small-form-factor PCs, HTPCs or low-power workstations that need reliable ATX power delivery in a tight chassis.

Replaces larger ATX units or older SFX supplies

This unit replaces a standard ATX power supply when space is limited or upgrades an ageing SFX unit that no longer delivers stable voltages. The jump is worthwhile when your current supply cannot fit the case or shows signs of voltage droop under load.

Verify SFX mounting clearance and connector count

Check that your case accepts SFX dimensions and that the included cables cover every component you plan to power. Confirm the motherboard, CPU and GPU connectors match your hardware before ordering.

Questions about this item

Does the KHACHIMO ST350-SFX fit standard SFX mounting holes?

Yes, the SFX form factor uses the standard mounting pattern, so it secures to any SFX-compatible case bracket with four screws.

What is the main installation step that gets missed with the FSP350-60GHS unit?

Connect the 24-pin ATX cable fully until the latch clicks; a loose seat causes intermittent power.

When should the internal fan on this 350 W supply be cleaned?

Blow dust out of the fan grille every six to twelve months, or sooner if airflow noise increases.
